Magnetite - an overview | ScienceDirect Topics

Magnetite is one of the end members of the ulvospinel-magnetite solid solution series (Fig. 3.3) and is the most common magnetic mineral on Earth.Magnetite is a cubic mineral with inverse spinel structure. The disordering (Curie) temperature varies more or less linearly with Ti content from -150°C for ulvospinel to 580°C for magnetite (Fig. 3.4 a).

Jacobsite-Magnetite Series. Magnesioferrite-Magnetite Series. Magnetite is an important, strongly magnetic iron ore, along with hematite. Nanoinclusions of magnetite crystals cause the iridescence of Rainbow obsidian (Nadin, 2007). Extremely thin layers of 200-nm octahedral crystals of magnetite give some basalt surfaces an iridescent sheen (Nadin, 2007).

1994-6-1 · Magnetite, Fe3O4 is produced abiotically and biotically. Abiotically, magnetite is a late magmatic mineral and forms as a consequence of the cooling of iron rich magma. Biotically, magnetite is produced by several organisms, including magnetotactic bacteria. Hematite, Fe2O3, is also produced abiotically and biotically. Abiotically, hematite rarely occurs as a primary mineral in igneous rocks ...

Magnetic Mineral - an overview | ScienceDirect Topics

The most common mineral is magnetite (T c = 580°C) but often there are Ti ions present and these give the titanomagnetite solid solution series (1-x)Fe 3 O 4.xFe 2 TiO 4 where x varies from 0 (magnetite) to unity (ulv öspinel). The Curie point falls as the Ti content increases.

Magnetite in the human body: Biogenic vs. anthropogenic

2016-10-25 · Magnetite is an iron-oxide mineral that occurs naturally on Earth. Because it is also an important component of many anthropogenic materials (e.g., coal fly ash) and synthetic products (e.g., black toner powders), magnetite can be released to the environment through human activities (1). In PNAS, Maher et al. (2) describe the abundant presence in the human brain of magnetite nanoparticles ...

Magnetite - WikiMili, The Best Wikipedia Reader

2021-3-7 · Magnetite reacts with oxygen to produce hematite, and the mineral pair forms a buffer that can control how oxidizing its environment is (the oxygen fugacity). This buffer is known as the hematite-magnetite or HM buffer. At lower oxygen levels, magnetite can form a buffer with quartz and fayalite known as the QFM buffer.
